limerick: [19] The best-known writer of limericks is of course Edward Lear, but ironically the term limerick was not born until after Lear was dead. It is first recorded in 1896, and is said to have come from a Victorian custom of singing nonsense songs at parties, in the limerick rhymescheme (aabba), which always ended with the line ‘Will you come up to Limerick?’ (Limerick of course being a county and town in Ireland).
